UNITED STATES DOMENICK RUFF, OF YOUNGSTOWN OHIO.

SPRING-REWINDING MACHINE.

Application filed September 14, 1921. Serial No. 500,668.

T all whom it may concern:

Be it known that I, DOMENICK RUFF, a citizen of the United States of America, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Spring-Rewinding Machines, of which the following is specification.

This invention relates to a device for rewindlng sprlngs.

The principal object is toprovide a machine that will rewind broken springs, and especially springs of fiat steel construction. Often times springs of this kind, used for energizing a motor or other mechanical movement, break at the inner end, which has been weakened by reason of a hole cut or punched therein for fastening purposes. In doing this my machine rewinds the spring in reverse order from the original winding, thereby reversing the inner broken end to the outer end where the same may be recut or punched.

Another objectis to effect a great saving of springs of this kind for greater use. It has been the practice of repair-men to throw away springs having the inner end broken.

The drawing illustrates a preferred em-' bodiment of the invention. However, it is to be understood that in adapting the same to meeting different conditions. various changes in the form and minor details of construction may be resorted to without departing from the nature of the invention as claimed and set forth in the drawings:

Figure 1 is a side elevation of the machine.

Figure 2 is a detail perspectiveview.

Figure 3 is a detail side View of spring being rewound in reverse order.

Figure 4 is a detail view.

Figure 5 is a vertical end view of the machine with parts cut away;

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by like reference characters.

By referring to Figures 1 and 5 it will be seen that the machine may have any suitable base 1. Secured to this base 1 are brackets 2. Through these brackets 2 and the side plates 3 and spacer tubes 4. pass bolts 5 and 6.

By means of these parts above described the frame work Br the machine is made.

Within this frame a U-shaped guide member 7 is suspended by means of a shaft 8 which 1s ournaled at points 9 in the side plates 3. This shaft 8 is provided with a crank 10 and a handle 11.

In operating this machine the U-shaped guide member is placed in position. The stud 12 passing through an elongated opening 13 of the left arm of the U-shaped guide member 7 and through a similar openmg of the left side plate 3. 8 is held in position by means of a keeper 141 which travels in-a circular groove 15 formed in the end 16 of the shaft 8. The crank end of the shaft 8 is provided with a ratchet 17 secured thereto.

under rest 19 and an upper rest 20. The outer end 21 of the spring-22 is now placed on the machine as shown in Figure 3.

It will be seen that the spring 22 will crowd down and slide on the tubes 4 held in position bymeans of the bolts 6.

When the spring has been rewound in a reverse direction the inner broken end 23 now becomes the outer end and may be held from thenatural tendency to rewind by means of a clamp 24 which is slipped over theouter circumference of the now rewound sprlng 22. The broken end 23 may now be readily repunched or cut for fastening purposes. 1

What I claim is:

In a device of the class described, two vertical side plates, four bolts holding said side plates in a vertical position, a shaft journaled in said side plates, a stud on said shaft for the purpose of holding a spring end, a keeper member registering with a circular groove on the outer end of said shaft, a ratchet secured to said shaft, a dog registering with said ratchet, crank and handle for said shaft, in combination with a U-shaped guide member supported be tween the two side plates by said shaft, subgtanltiially as described for the purpose set ort In testimony whereof I aflix my signa-- ture.
